The recently reported microlensing events of the Large Magellanic Cloud (LMC) have caused much excitement, and have been interpreted as due to 'dark objects' called massively compact halo objects (MACHOs) in the halo of our Galaxy. It is shown here that stars within the LMC play a dominant role as gravitational lenses and can indeed account for the

Spitzer Space Telescope Infrared Array Camera imaging provides an opportunity to study all known morphological types of galaxies in the mid-IR at a depth significantly better than ground-based near-infrared and optical images. The goal of this study is to examine the imprint of the de Vaucouleurs classification volume in the 3.6 μm band, which is

The direct detection of extrasolar planets is the only technique that leads to the most complete characterization of their physical properties. Here, we report on mid-IR observations of five directly imaged substellar companions (DF Tau B, FU Tau B, κ And b, GJ 758 B, and GJ 504 b) obtained with the Si-2 filter (8.7 µm) in the CanariCam instrument

The goals of the S4G project are described by Sheth et al. (2010, submitted). (1 data file).

Most of the V-types that are known are located in the inner main belt and are members of the Vesta collisional family. The analysis of the photometric and spectroscopic properties of asteroids inside and outside the Vesta family, including V-types in the middle and outer main belt, can answer questions about the existence of differentiated bodies

We present reflectance spectra of 19 V-type asteroids obtained at the 3.6 m Telescopio Nazionale Galileo covering 0.8 to 2.5 μm. For 8 of these asteroids we obtained also visible spectra in the same observational run. The range from 0.8 to 2.5 μm, encompassing the 1 and 2 μm pyroxene features, allows a precise mineralogical characterization of
